Need a hand with blender

[JoshMX1996]

So i have been making my own skins for a while now and recently have been interested in renders. after doing some research on how its done i can only find really old videos and the current version of blender looks completely different so it is confusing was wondering if anyone could explain it a little better too get me up and running?. Add me on discord Rydor75#5459 thanks
